TO ALL WHOM IT MAY CONCERN: ,1 v

Be it known that I, J. H. RICHARDSON, of Philadelphia, in the county ofPhiladelphia, fand ,State of Pennsylvania, have invented a new andimproved Lantern 'and that the following description, taken inconnection with the accompanying drawing; hereinafter referred to, formsa' full and exact speciiication of the same, wherein I have set forththe nature and principles of my said improvements, by which my inventionmay be distinguished c from all others of a similar class, together withsuch parts as I claim, and desire to have secured to me by LettersPatent. Y

3( This invention relates Vto a new and wimproved lantern designed moreespecially for ship and railroadlanterns.

' 'The invention consists in feeding the flame with oxygen from the topof the-lantern, a direct draught upward from the bottom through the topofthe same being avoided, wherebythelame will not be liable to beextinguished by gusts ofwind o`r the swinging of the lantern, as is nowthe case withIthosc which have a draught of air passing through themfrom the bottom upward, and are exposed to or carried. in the openl air.

The accompanying drawing represents a vertical central section of myinvention. i A represents the metal base of thelantern, B the glassglobe, C ,the metnl'tnp'or cap, D the guards, and E the handle. F is thelamp, which'is-secured in the metal base A by any lsuitable catch orfastening., The

lamp is. encompassed by u double wall,a a, the space between which issupplied with cotton-waste or any suitable material, b, which will servefor a pack-ing on which the metal rim c, on the lower end o f the'glassglobe B, and

the lower end of B rest or bear, as shown clearly in the drawing.

By this arrangement the lamp is ,tted intofthe lower end ofthe lanternperfectly air-tight, nol holes or l perforations of any kind being vmadein the lower part of the-lantern to admit the air.

The metal top or cap C of the lantern is perforated' with holes d allaround, and thislcap is provided with afpendelnt conical tube, G, whichextends down within theA glassfglobe B,'and is covered by a plate, e,some distance above the top oi' the cap, with an ppeningall around,.between e and the top of the cap, to admit .of the escape of the warm,vitiated air from the lamp,.the pure air which feeds the flame -passingdown through the perforations d in the side of the top or cap C, asshown bythe arrows 1, theY passage of the `vitiated air being shown bythe arrows 2.

'By this Aarrangement the'ilameof the lampl will be abundantly suppliedwithfair, and not liable to be adected or extinguished bysudden gustsof. wind when hung or carried in exposed situations. Having thusdescribed my invention, I claim as new, and desire lto secure by LettersPatent- -1. The perforated cap C, in combination with a lamp, F, fittedwithin or uponl the base A of a lantern, substantially as and for thepurpose specified. i l 2. I claim .the double walls a a, when .filled inwith suitable material to form an air-tight joint, in combination withthe globe or chimney B and ring c, encircling the base of the same,substantially as herein shown and described. l

3. I claim the tube G and plate e, iu combination with globeB andanair-tight joint around the lamp F, substantially as and for the purposeset forth. Y

The above specification of my invention signed by me, this 30th day ofApril, 1867.
